How ever, the other day when finally understanding what bandlimited wave creation is (i am a noobie, been doing DSP stuf on and off for a half/year) it hit me i can implement one little part in my synths. It's all about the freq (that i knew), very simple you can reduce alias (the alias that you can hear that is) extremely by keeping track of your frequence, the way i solved it is using a factor, afact = 1 - sin(f*2PI). This means you can do audiable alias free synthesis without very complex algorithms or very huge tables, even though the sound becomes kind of low-filtered.
Propably something like this is mentioned b4, but incase it hasn't this is worth looking up

I'm new to that DSP stuff and can't get the key to
what'S the meaning of afact? - Can you explain please!? - Thanks in advice!

Added on : 16/04/04 by druttis[ AT ]chello[ DOT ]seComment : afact is used as an amplitude factor for fm or fb depending on the carrier frequency. The higher frequency the lower afact. It's not completely resolving the problem with aliasing but it is a cheap way that dramatically reduces it.
